The new object, which was confirmed at V = 17.6 on three stacked 90-s exposures taken with a 0.40-m telescope at Observatorio Astronomico de La Sagra on Aug. 2.987, is located at R.A. = 20h45m39s.51 +/- 0s.01, Decl. = -5d35'11".8 +/- 0".8 (equinox 2000.0), which is 5" west and 10" north of the nucleus of the galaxy PGC 65331. Nothing is visible at this position on a Digitized Sky Survey image from 1985 July 11 (limiting red mag 22) or on a Sloan Digital Sky Survey image from 2000 Sept. 3 (limiting I mag 23).
